' JACOBKHEINRIGH ivirssoive, or FRANKFURT;oN-Trria-MIN, GERMANK p STEAMLENGINE.

T all whom it may concern l l Be it known that I, JACOB HEINRICH' MissoNe,'head engineer, asu'bject of theGerman Emperor, and resident ofy Frankfort-on-the- Main,`Germany, with the postfoiiice address Oederweg No.` 1261 have inventednew.v and useful Improvements in Steam-Engines, ofl

which the following is a specilication.

, .The object of my invention is the construction of a simple and effective steamengine having an action'analogous to an en-V 'c gine of the compound type and refers more especially to the means, whereby a common steam cylinder iitted with a common piston and piston rod may be soiworked, that one side of the cylinder-acts under highr pressure steam from the boiler, whereas the expanded steam passes directlyy or through lalreceiver to the other side of the cylinder to act there lowvpressure side, whereas,

very much as inthe low 4pressure cylinder of the well known compound venginesffA part only of the steam expanded' at the high pressure kside o'f the cylinder is admittedatothe the restv 'of the expandedk steam isjdisposedyof in various ways, which may beused' separately vor combined. One means to dispose of this remain- `ing steam is yto discharge it from the jrece-iver forheatingor' for any'other desired purposes. `Another means is to compress partof the expanded steam and force it backwardinto the'live lsteam pipe to the boiler. i' A s 'In the drawings Figures l and 2 arey longitudinal sections, "part' elevation and largely diagrammatic of "two arrangements of an engine cylinder and associated vvdevices embodying my .invent-ion.

Referring t@ Fis. 1, a isa@ Cyiindet'ff uniform diameter, the piston also of uniform diameter throughoutl and preferably about half the length `,of the cylinder, c the high pressure side, and d the low pressure side. Valves g and c being closed and "valve e opened, steam enters at e, is cut. otf

whenthe piston has moved a suitable distance, then expands. and finally, at the end of the stroke, is discharged and passes, either partially or completely, through passage f and valve g (which is now opened) into the receiver z which envelops the cylinder ai.`

Valves e and g are both provided with governors; in the arrangement shown a single pressure governor rf controls both these valves but separat-e governors `may be used if desired and the governor' or governors Specification 'of Letters Patenti i Application filed February 2,8, 1911.

` passes'into receiver it, as

scribed, valve -c which is controlledby a centrifugal governor owis'opened' so that the amountof workl done cylinderl side,

may be of'any usual type. From thereceiverllnrpipe connection la is made tothe heating or other arrangement 7a2 for the utilization of steam@ When the piston reaches the end of its stroke and steam has just been desteam from It passes through passage f2 and valve la to the low pressure side CZ.' The steam pressures upon the ltwo sides ofthe pistonl will then be substantially equal. After the piston has advanced aV short distance valve is closes'andv the-steam charge on the low pressure side expands'during the fur-r ther advance of the piston thus lessening, by

duringsuch expansion, the work which the ily. wheel must do in carrying'the piston back to the starting point. Exhaust finally takes place through the'valve `Z. Any overflow valve/m, is kept constantly closed `by thelive steam pressure applied through passage f3. `lVhe'n the valve g'closes so early that thepiston compresses theexpanded stearnon the high pressure side backftothe initial live lsteam v pressure before the cylinderx-end is reached, and this time of closure will be earlier or latervaccording fasless or more steam is needed by the'heatin'g or other arrangement 7a2, this overlowvalve mwillopen `and the l compressed steam flow back pipe through passageyi?.l

Fig, 2 represents kthe same arrangement yas Fig. l except that the centrifugal governor into the Vsupply sure `and low pressure inlet while the pres' surefgovernortaf-acts only `upon the exhaust valve g of the high pressure side. The mode of operation (is as just` described for the arrangement of Fig. 1.

Now what I claim and desire to secure'by Letters Patent is the following:
